York S1-9951-1061 Orifice

The York S1-9951-1061 Orifice is a precision-engineered OEM replacement part designed for burner assemblies in York HVAC equipment. This specific .106 Dia Orifice LP is critical for maintaining the correct manifold pressure and fuel-to-air ratio in liquid propane (LP) conversion applications. By replacing the standard natural gas orifice with this accurately bored 0.106-inch diameter component, technicians ensure stable burner ignition and precise gas delivery, which prevents incomplete combustion and carbon buildup. As a genuine furnace burner orifice, it meets strict manufacturer specifications for flow rate and material durability, ensuring compatibility with your existing manifold and burner tube configuration. Proper sizing is essential for system efficiency; utilizing an incorrect diameter can lead to frequent short-cycling or thermal limit tripping. Optimized for low-pressure LP systems, this brass orifice provides the reliability required for multi-stage heating equipment and high-efficiency furnaces.

• Precise 0.106" Diameter: Ensures accurate BTU input for consistent heating performance.
• LP System Compatibility: Specifically designed for stable combustion in liquid propane furnace applications.
• Direct OEM Fit: Replaces York S1-9951-1061 without the need for additional modifications or boring.
• Durable Brass Construction: Resists thermal stress and corrosion within the burner compartment.
• Optimized Gas Flow: Minimizes the risk of sooting and ensures a clean, blue flame profile.

• Can I use this orifice for natural gas systems? No, this is a designated LP gas orifice. Natural gas requires a larger diameter to compensate for its lower energy density compared to liquid propane.
• Is this compatible with other HVAC brands? While designed for York, it fits specific furnace models where the manifold and burner specifications match York S1-9951-1061 technical data.
• When should I replace my burner orifices? Replacement is necessary during a natural gas to LP conversion or if existing orifices show signs of clogging or improper flow.
